“We know that not all people with diabetes are looking for a wearable continuous glucose monitoring device to manage their diabetes."

Okay that's pretty bogus. Some people can't afford it, but everyone with diabetes would benefit from a CGM. There's much more to be gained from trends in CGM data than singular data points. (I was diagnosed with Type 1 at 16, been on a CGM for most of that time).

The device claims to have 97% of reading within 15% of the Freestyle Libre, which itself is then not as accurate as blood glucose.

Put another way, it’s less accurate than a device that’s already less accurate than finger sticks.

Given this info, I’m not sure this version is practically useful yet in terms of accuracy.

Are you looking to transition from your current CGM to a wearable one at the first opportunity?

The Dexcom G6 is the best CGM on the market, but its sensor filtering (Kalman or particle?) has smoothness and/or continuity priors that cause persistent inaccuracies.

I observe these persistent inaccurate states on the fifth or sixth day using a sensor. Calibration doesn't help. The reading goes wrong and stays wrong.

It probably happens to you, too, but anyone who doesn't test with a glucometer will likely not notice the failure. You will be harmed by these inaccuracies. Persistent inaccuracy is different than the Gaussian (normal) error of a glucometer, which is far more benign.

Also, CGMs are slow. The reading is based on interstitial fluid and lags direct blood glucose test by 15 minutes or more.

I have completely abandoned the Dexcom G6 and have gone back to 16x daily finger stick blood testing. I am also on a low-carb/high-fat diet, which makes it easy to maintain normal human blood glucose. My HbA1c has been 4.9 for a decade.

I was overjoyed to use the CGM at first, but it turned out to be a net loss. If you want to control your diabetes, use a glucometer and adhere to a strict low-carb/high-fat (ketogenic) diet.

A completely non-invasive device even getting close to the accuracy of finger stick or implanted devices is a big deal.

Is there a good source for info on ketogenic diets for type 1 diabetics? My youngest has been on pump therapy for the past 5 years and is completely burnt out from all of the alerts and scares (some of it is self inflicted). She was on a medtronic closed loop system for 4 years and that was the source of most of her frustration. She's on g6+tslim now which has been much better, but she still falls off the wagon regularly.

I just think a keto diet would make it easier for her, but I'm seeing all sorts of conflicting info on it and her doctors don't support it. I've done it a few times in the past and getting started is the hardest part. I'd like for her to try but I'm getting no support on the idea. ?

Keto is generally best once you've finished developing. If she's under 18, I wouldn't do Keto.

Dr. Phinney's lectures (Virta Health) are a good resource. Here's the first one, it's easy to find the rest:

Your fat sources should be nuts and olive oil and chia seed, with some cheese and egg.

Healthy food with lots of healthy fat.

The brain uses ketones as fuel, so you will find that hypoglycemia is easily handled. In ketosis, your brain will have plenty of fuel, even if your blood glucose drops too low.
